Implement 3D texture read/write via storage usage on D3D12

The main part of this change is to add a few end2end tests, with
some renaming stuff like arrayLayerCount to sliceCount in order to
include both 2DArray and 3D textures.

The implementation is quite simple: just set UAV descriptor on D3D12.

The new tests can pass on Vulkan and Metal, which indicates the
implementation has been done on them.

The new tests fail on OpenGL and OpenGLES. I will take a look and
submit separate patch for GL and GLES.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs:
    • D3D12 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
